A comprehensive method for the trace determination of four stilbene-type disulfonate and one distyrylbiphenyl-type fluorescent whitening agents (FWAs) in environmental water samples was developed and validated. Various solid-phase extraction (SPE) cartridges were investigated. The newly developed Oasis WAX (weak mixed-mode anion exchange and reversed-phase… CONTINUE READING
